comfort criteria for buildings

(OP)
i have previously posted this under the moment frame and shear wall thread but got no responses... so try again! smile

i am starting on the design of a number of tall buildings, ranging in heights from 25-50 storeys and am aware that i need to design the stability systems to ensure that accelerations from wind are kept to allowable limits.

I have a few queries on this and welcome any comments:

1/ where can i find some stated limits, preferably from codes, on what acceptable accelerations are and for what return period. I have read and heard people discuss values like 12-15 mg for residential buildings, 18-20 for offices, but i would like to see some solid evidence of these limits particularly limits tied into a return period for the wind

2/ are there any limits on rotational movement, ie when a floor plate twists torsionally on plan from wind. ie radians/second or degree/second

3/ how can i calculate accelerations, particularly at the concept stages of design, before a wind tunnel test is carried out

many thanks in advance
